What is 'SSM' and why is it critical for cobots?

• A. System Safety Monitoring.
• B. Speed and Separation Monitoring; ensures safe operating distance between cobot and humans.
• C. Sensor Signal Modulation.
• D. Safe Sequence Management.

Answer: (D)

Speed and Separation Monitoring is about keeping a safe distance between humans and the cobot by continuously tracking how far apart they are and how fast they’re moving. The cobot uses sensors (like cameras, LiDAR, or pressure/force sensing) to monitor the workspace and, if a person gets too close or moves unpredictably, it can slow down, stop, or adjust its path to maintain a safe gap. This dynamic safety measure is essential in shared work environments because people aren’t predictable, and rigid safety zones can’t adapt in real time. By actively managing how fast the cobot operates in relation to nearby humans, SSM reduces the risk of contact, supports smoother collaboration, and helps meet safety standards for human–robot interaction. Safe Sequence Management, while sounding like it could relate to ordering actions safely, isn’t the term used for this real-time proximity safety behavior.
